Abstract
Display effects of symbols may enhance expectation of a player with “mecha-reels” and video reels in a superposed manner. Symbol images and symbols are displayed statically in variable display windows 22, 23, 24 in a state of disenabling a transmissive display of reels and/or in a state of enabling the transmissive display of the reels after one of patterns A, B, C, and D, in which each display window is made in either transmissive state or non-transmissive state based on sampled random numbers and a table setting for each winning combination of the selected symbols such that the variable display windows 22, 23, 24 of the lower display device 4 would be switched between in the transmissive state and in the non-transmissive state so as to make the reels disposed behind the variable display windows 22, 23, 24 between visible and invisible.
Description
- This application is based upon and claims the benefits of priorities from Japanese Patent Application No. 2005-262124 filed on Sep. 9, 2005, the entire contents of which are incorporated herein by reference.
- The present invention relates to a gaming machine in which a game is played with symbols to be displayed variably and stopped to be displayed statically.
- In a conventional gaming machine, for example, a slot machine, a plurality of reels are rotated mechanically such that, when a combination of symbols being displayed statically after the reels are stopped includes any one of winning combinations, a payout corresponding to such a winning combination is paid out (refer to Japanese unexamined patent application publication No. 2003-284809).
- Also, in a slot machine recently being introduced, a video reel which displays variably various kinds of combinations of symbols by images and stops such variable display of combinations of symbols so as to display a combination of symbols statically may be employed instead of the above-mentioned reels rotating mechanically (to be referred to as “mecha-reel”).
- However, in either slot machine, the “mecha-reel” or video reel is employed alternatively to display a combination of symbols such that display effects of the combination of symbols to be displayed variably and stopped to be displayed statically are performed in a uniform manner so as not to appeal to players.
- In the present invention, in considering the above, a gaming machine may be provided such that the mecha-reel and the video reel are employed in a superposed way therein so as to agitate expectations of the players by display effects of the combination of symbols.
- According to the present invention, a gaming machine comprises: a plurality of display windows being composed of a video display which can display variably and statically images of a plurality of symbols; a plurality of mechanical reels being disposed behind the plurality of display windows, respectively, and being composed of peripheral surfaces on which a plurality of symbols are disposed, the plurality of symbols being displayed variably and statically through the plurality of display windows as the windows are in a transmissive state; and a processor in communication with the display windows and the reels. The processor is operable to: (a) select a plurality of symbols to be displayed statically as a game result by lottery; (b) determine whether each of the plurality of display windows is made in the transmissive state or a non-transmissive state based on a combination of the selected symbols; (c) display symbols of reels through corresponding display windows in the transmissive state and images of symbols on display windows in the non-transmissive state as the game result; and (d) award a player based on the game result when the game result corresponds to a predetermined winning combination of symbols.

In addition, a pair of coldcathode ray tubes 43 is provided to the upper and lower portions of the back side of theopenings 38A to 38C of therear holder 38. The cold cathode ray tubes illuminate the symbols formed on the outer peripheral surfaces of thereels 220. - The liquid crystal panel 33 is a transparent electrical display panel composed of ITO or the like which is provided on the front panel of the
reels 220 and through which thereels 220 are visible. The back side of the area around the display windows is held in theliquid crystal holder 34. Thelight guide 36 comprises an optically transparent resin panel and is provided with a lens-cut which allows the light emitted from the coldcathode ray tubes 42 located on the side to pass to the back side of the liquid crystal panel 33. Thediffusion sheet 35 comprises an optically transparent resin panel that diffuses the light guided by thelight guide 36, and makes uniform the light irradiated onto liquid crystal panel 33. Thediffusion sheet 35, thelight guide 36, and theliquid crystal holder 34 for holding the liquid crystal panel 33 are integrated, and the peripheral surfaces thereof are inserted into thebezel metal frame 32. Through this insertion, a front side of a display component of the liquid crystal panel 33 is held in thebezel metal frame 32. - The peripheral surfaces of the
liquid crystal holder 34, thediffusion sheet 35, and thelight guide 36, which have been integrated by being fitted into thebezel metal frame 32, are further inserted into thereel glass base 31, and are held by thereel glass base 31, with the front side of the display component of liquid crystal panel 33 open. Thetransparent panel 30 is bonded by compression to the front side of thereel glass base 31 and superposed on the front side of the display component of the liquid crystal panel 33 by mounting of thereel glass base 31 onto themachine front panel 20 viascrews 41. - The

Therear holder 38 also functions as a reflector whereby the light emitted by the coldcathode ray tubes 42 toward thelight guide 36 is reflected onto the liquid crystal panel 33. Theantistatic sheet 39 is transparent, is attached to the back side ofrear holder 38 by double-sided tape, and covers the back side of theopenings 38A to 38C formed in therear holder 38. - Various kinds of symbol combinations used in the game are formed on the peripheral surfaces of the
reels 220, as shown inFIG. 7A .FIGS. 7A shows columns of symbols which are variably displayed during the game and are scrolled down in thevariable display windows 22 to 24 of the lowerliquid crystal display 4. InFIG. 7A , the column ofsymbols 241 represents a symbol set which is variably displayed in thevariable display window 22, the column ofsymbols 242 represents a symbol set which is variably displayed in thevariable display window 23, and the column ofsymbols 243 represents a symbol set which is variably displayed in thevariable display window 24. - Here, the columns of
symbols 241 to 243 are identical to each other, and each column of symbols constitutes 11 symbol combinations appropriately formed from atriple BAR 91,cherry 92,double BAR 93, seven 94,single BAR 95, and blank (region in which no symbol is present) 96. - When forming various types of symbol combinations on the peripheral surfaces of the
reels 220, a common procedure is adopted in which 11 symbol combinations are printed on long reel sheets that have corresponding features to the width and circumference lengths of thereels 220, and the reel sheets are then attached to the peripheral surface of thereels 220. It is apparent, however, that it is also possible to form the symbols by using a different procedure. Further, the same columns ofsymbols 241 to 243 are employed for vide reels such that symbols are displayed in any of thevariable display windows 22 to 24. -
FIG. 7B also shows various kinds of symbol combinations of another embodiment which can be used in the game to be displayed on thevariable display windows 22 to 24 when thevariable display windows 22 to 24 become non-transmissive. - In the following, an explanation of a structure related to the control system of the
slot machine 1 is made with reference toFIG. 5 .FIG. 5 is a block diagram schematically showing a control system of the slot machine. - In
FIG. 5 , the control system of theslot machine 1 is basically configured with theCPU 50 as a core component; andROM 51 andRAM 52 are connected to theCPU 50. TheROM 51 stores a main process program to be described later, a start acceptance process program, a payout program, a game process program, a lottery table for selecting symbols to be stopped and displayed statically, and other various programs necessary for controlling theslot machine 1 and the data tables. TheRAM 52 is memory which temporarily stores various kinds of data having been computed by theCPU 50. - A clock
pulse generating circuit 53 for generating a basic clock pulse and afrequency divider 54 are connected to theCPU 50. Arandom number generator 55 for generating random numbers and arandom sampling circuit 56 are also connected to theCPU 50. The random numbers which are sampled through randomnumber sampling circuit 56 are utilized for various kinds of winning combinations and other lottery drawings. Furthermore, theCPU 50 is also connected to thespin switch 58 attached to the spin (“SPIN/REPEAT-BET”)button 12; the 1-BET switch 59 attached to the 1-BET button 11; the 3-BET switch 60 attached to the 3-BET button 13; the 5-BET switch 61 attached to the 5-BET button 14; the change (“CHANGE”) switch 62 attached to thechange button 6; the payout (“CASH-OUT”) switch 63 attached to thepayout button 7; and the help (“HELP”) switch 64 attached to thehelp button 8. TheCPU 50 controls operations that correspond to each button on the basis of the switch signals which are outputted from the above switches. - Three
step motors 68 for rotating thereels 220 via amotor driving circuit 167 are connected to theCPU 50. A positionchange detection circuit 69 is also connected to theCPU 50. When theCPU 50 outputs a motor drive signal (command pulse) to themotor driving circuit 167, each of thestep motors 68 is rotated and driven by excitation signals outputted from themotor driving circuit 167. Thereels 220 are thereby rotated. - At this time, the
CPU 50 counts the number of drive pulses supplied to each of thestep motors 68. TheCPU 50 determines the rotational positions of the symbols on thereels 220 based on the number of drive pulses counted, controls the stop positions, and the like. - A position
change detection circuit 69 is connected to theCPU 50. The positionchange detection circuit 69 detects changes made to the stop positions of thereels 220 after they have been controlled to stop by themotor driving circuit 167. - Furthermore, the
coin sensor 65 provided to thecoin insertion part 9 and thebill sensor 66 provided to thebill insertion part 10 are connected to theCPU 50. Thecoin sensor 65 detects the coins inserted intocoin insertion part 9, and theCPU 50 computes the number of the inserted coins on the basis of the coin detection signal outputted from thecoin sensor 65. Thebill sensor 66 detects the kind and amount of the bill inserted into thebill insertion part 10, and theCPU 50 computes the amount of the bill and the number of coins equivalent to the bill, based on the bill detection signal outputted from thebill sensor 66. - A
hopper 71 is connected to theCPU 50 via ahopper driving circuit 70. When the CPU outputs a drive signal to thehopper driving circuit 70, thehopper 71 pays out a predetermined number of coins from thecoin payout opening 15. - The
coin detector 73 is connected to theCPU 50 via a payoutcompletion signal circuit 72. Thecoin detector 73 is provided to the inside of thecoin payout opening 15. Thecoin detector 73 outputs a coin payout detection signal to the payoutcompletion signal circuit 72 when it has been detected that a pre-determined number of coins has been discharged through thecoin payout opening 15. The payoutcompletion signal circuit 72 outputs a payout completion signal to theCPU 50 based on these signals. Furthermore, the upperliquid crystal display 3 and the lowerliquid crystal display 4 are connected to theCPU 50 via a liquidcrystal driving circuit 74, and the upperliquid crystal display 3 and the lowerliquid crystal display 4 are controlled by theCPU 50. - The liquid
crystal driving circuit 74 comprises aprogram ROM 81, animage ROM 82, animage controller CPU 83, awork RAM 84, a VDP (Video Display Processor) 85, avideo RAM 86, and the like, as shown inFIG. 6 . Programs stored in theprogram ROM 81 control the images displayed on the upperliquid crystal display 3 and the lowerliquid crystal display 4, as well as various kinds of selection tables. Theimage ROM 82 stores, for example, audiovisual presentations made by the upperliquid crystal display 3 and the lowerliquid crystal display 4, various types of help information displayed by the upperliquid crystal display 3, the symbol sets 241 to 243 shown inFIG. 7 and displayed in thevariable display windows 22 to 24 of the lowerliquid crystal display 4, and other image-forming DOT data. Theimage controller CPU 83 determines, from among the DOT data stored in advance in theimage ROM 82, the images to be displayed by the upperliquid crystal display 3 and the lowerliquid crystal display 4. The determination is made according to the image control program stored in advance in theprogram ROM 81, and is based on the parameters set by theCPU 50. Thework RAM 84 is structured as temporary memory means when the image control program is executed by thecontrol CPU 83. TheVDP 85 forms images according to the displayed content selected by theimage control CPU 83, and outputs the images thus formed to the upperliquid crystal display 3 and the lowerliquid crystal display 4. Therefore, for example, the symbol sets 241 to 243 shown inFIG. 7 are variably or statically displayed in thevariable displays 22 to 24 (refer toFIG. 2 ). Thevideo RAM 86 is structured as temporary memory means for forming images by theVDP 85. - In the
slot machine 1 according to the present embodiment, thevariable display windows 22 to 24 (refer toFIG. 2 ) of the lowerliquid crystal display 4 can be made transmissive or non-transmissive by the liquidcrystal driving circuit 74. Furthermore, during the game thereels 220 located on the back side of the variable display windows are rotated and stopped by themotor driving circuit 167 in thevariable display windows 22 to 24 (refer toFIG. 2 ) in a transmissive state. Therefore, the symbol sets 241 to 243 (refer toFIG. 7 ) formed on the peripheral surfaces of thereels 220 are statically displayed after being variably displayed by scrolling. This is achieved using the transmissivevariable display windows 22 to 24(refer toFIG. 2 ), through which thereels 220 are visible. In the non-transmissivevariable display windows 22 to 24 (refer toFIG. 2 ), the liquidcrystal driving circuit 74 statically displays the images of the symbol sets 241 to 243 (refer toFIG. 7 ) on the nontransmissivevariable display windows 22 to 24 (refer toFIG. 2 ) through which thereels 220 located on the back side of the variable display windows are not visible. This occurs following the variable display of the images by scrolling. - Regardless of the transmissive or non-transmissive state of the
variable display windows 22 to 24, the three symbol sets 241 to 243 are statically displayed in thevariable display windows 22 to 24 when the goal is to cause the symbol sets variably displayed by scrolling to be statically displayed. - Various kinds of winning combinations are preliminarily set based on the combination of multiple types of symbols. When a combination of symbols corresponding to a winning combination is stopped on the pay line L, coins are discharged according to the winning combination through the
coin payout opening 15. In this regard, the present slot machine functions in the same manner as a traditional slot machine. Therefore, an explanation regarding this point is omitted. - Referring back to
FIG. 5 , anLED 78 is connected to theCPU 50 via anLED driving circuit 77. When various types of presentations are made on the front side of theslot machine 1 with a multiple number of LEDs provided thereto, theLEDs 78 are controlled so as to be lit by theLED driving circuit 77 based on the drive signals from theCPU 50. Moreover, asound output circuit 79 and aspeaker 80 are connected to theCPU 50. Thespeaker 80 generates various types of sound effects based on the signal outputted from thesound output circuit 79 when various types of presentations are made. - In the following, an explanation with reference to
FIG. 8 regarding the lottery table used to determine the symbols which are to be statically displayed on the pay line L when conducting a game in theslot machine 1 by using the threevariable display windows 22 to 24.FIG. 8 is an explanatory diagram showing the lottery table for the symbols to be statically displayed when a game is played using the three variable display windows. The lottery table shown inFIG. 8 is stored in theROM 51. - The symbols to be statically displayed on the pay line L are determined for each of the
variable display windows 22 to 24. In order to achieve the above, code numbers from “0” to “10” are assigned to the symbol sets 241 to 243 for each of thevariable display windows 22 to 24 (shown inFIG. 7 ), sequentially in order from highest to lowest. On the other hand, the lottery table as shown inFIG. 8 is be prepared. Three random numbers is sampled by the randomnumber sampling circuit 56 so as to correspond to each of thevariable display windows 22 to 24. - For the sake of convenience in the following explanation, the symbol sets 241 for the left
variable display window 22 are referred to as the “left reel,” the symbol sets 242 for the centralvariable display window 23 are referred to as the “central reel,” and the symbol sets 243 for the rightvariable display window 24 are referred to as the “right reel”. - As shown in the lottery table in
FIG. 8 , when the random number sampled through the randomnumber sampling circuit 56 falls within the range from 0 to 15, a blank 96 assigned to the code number “0” is statically displayed on the pay line L with regards to the “left reel” of the symbol sets 241 on the leftvariable display window 22. The same procedures apply below to the code numbers from “1” to “10,” based on the lottery table shown inFIG. 8 . - The same procedures as used with the “left reel” of the symbol sets 241 on the left
variable display window 22 apply to the “central reel” of the symbol sets 242 on the centralvariable display window 23, as well as to the “right reel” of the symbol sets 243 on the rightvariable display window 24. - The following is an explanation in reference to
FIG. 9 regarding the winning combination and the corresponding payout when conducting a game in theslot machine 1 using the threevariable display windows 22 to 24.FIG. 9 is an explanatory diagram showing the winning combination and the corresponding payout when conducting a game using the three variable display windows. The table shown inFIG. 9 is stored in theROM 51. - In
FIG. 9 , when the code numbers assigned to the “left reel,” “central reel,” and “right reel” are all either “4” or “9,” the combination “7-7-7” is won. In this case,sevens 94 are statically displayed on the pay line L in thevariable display windows 22 to 24, and the player obtains the payout of “100.” The same procedures apply below to the payouts of “5,” “3,” “2,” and “1,” based on the table shown inFIG. 9 . - When the code numbers assigned to the “left reel,” “central reel,” and “right reel” have a combination other than the combinations described above (namely, the combinations when the payouts are “100,” “5,” “3,” “2,” and “1”), a “losing combination” is obtained. In this case, either a
triple BAR 91, acherry 92, adouble BAR 93, a seven 94, asingle BAR 95, or a blank 96 is statically displayed on the pay line L in thevariable display windows 22 to 24, and no payout is given to the player. - The following is an explanation with reference to FIGS. 10 to 15 regarding the table which is used to determine the transmissive or non-transmissive state of the
variable display windows 22 to 24 when conducting a game in theslot machine 1 using the threevariable display windows 22 to 24. - In the present embodiment, determination as to whether the
variable display windows 22 to 24 are in a transmissive or non-transmissive state is made by selecting a pattern from among four patterns, in which thevariable display windows 22 to 24 are either in a transmissive or non-transmissive state, by using a table provided for each winning combination (refer to FIGS. 10 to 15) as well as random numbers within a range of 0 to 7 sampled by the randomnumber sampling circuit 56. - Prior to providing an explanation regarding the table shown in FIGS. 10 to 15, an explanation will be given regarding the four patterns in which the
variable display windows 22 to 24 are either in a transmissive state or a non-transmissive state. As shown inFIG. 1 , the four patterns are pattern A, pattern B, pattern C, and pattern D. In pattern A, all of thevariable display windows reels 220 are visible on any of thevariable display windows variable display window 22 is in a non-transmissive state, while thevariable display windows reels 220 are visible only on thevariable display windows variable display windows variable display window 24 is in a transmissive state. Therefore, the peripheral surfaces of thereels 220 are visible only on thevariable display window 24. In pattern D, all of thevariable display windows reels 220 are not visible on any of thevariable display windows - The following is an explanation of the tables shown in

The summation of all expectation values are shown in the bottom cell of the column. Therefore, it is expected to have 1.750 windows transmissive when the “BAR-BAR-BAR” winning combination is hit. -
FIG. 14 is an explanatory drawing showing a table used to determine the transmissive or non-transmissive state of the variable display windows in the case of hitting a “Cherry-Cherry-Cherry” when conducting a game using the three variable display windows. The table shown inFIG. 14 is stored in theROM 51. - Specifically, hitting a “Cherry-Cherry-Cherry” causes pattern C to be selected using the table shown in
FIG. 14 , when, for example, the random numbers sampled by the randomnumber sampling circuit 56 fall within a range of 2 to 6. It is therefore determined that all thevariable display windows FIG. 14 . - Here, the number of transmissive display windows, through which respective reels disposed behind may be seen, is three (3), two (2), one (1), or zero (0) for pattern A, B, C, or D as shown in
FIG. 11 . Therefore, each expectation value, which may be given by multiplying the probability by the number of transmissive windows, is listed on the right column in the table. The summation of all expectation values are shown in the bottom cell of the column. Therefore, it is expected to have 1.250 windows transmissive when the “Cherry-Cherry-Cherry” winning combination is hit. -
FIG. 15 is an explanatory diagram showing a table used to determine the transmissive or non-transmissive state of the variable display windows in the case of hitting “the losing combination” when conducting a game using the three variable display windows. The table shown inFIG. 15 is stored in theROM 51. - Specifically, hitting a “losing combination” causes pattern D to be selected using the table shown in
FIG. 15 when, for example, the random numbers sampled by the randomnumber sampling circuit 56 fall within a range of 3 to 7. It is therefore determined that all thevariable display windows FIG. 15 . - Here, the number of transmissive display windows, through which respective reels disposed behind may be seen, is three (3), two (2), one (1), or zero (0) for pattern A, B, C, or D as shown in
FIG. 11 . Therefore, each expectation value, which may be given by multiplying the probability by the number of transmissive windows, is listed on the right column in the table. The summation of all expectation values are shown in the bottom cell of the column. Therefore, it is expected to have 0.750 windows transmissive when the “losing combination” is hit. Since the player can recognize if the display window is transmissive or not during the variable display, the player expects that he may get a higher winning combination if the number of transmissive display windows is higher. - The following is an explanation of a main process program executed in the
slot machine 1, made with reference toFIG. 16 .FIG. 16 is a flowchart of the main process program. InFIG. 16 , the start acceptance process program to be described later shown inFIG. 17 is first executed in step (hereafter, abbreviated as “S”) 11. This is a process for accepting the switch signals outputted from the SPIN/REPEAT BET switch 58, 1-BET switch 59, 3-BET switch 60, and 5-BET switch 61, based on the operations of the SPIN/REPEAT BET button 12, 1-BET button 11, 3-BET button 13, and 5-Bet button 14. When this process starts, thevariable display windows - In S12, the lottery operation shown in
FIG. 18 is performed based on the switch signals outputted from the spin (“SPIN/REPEAT BET”)switch 58, 1-BET switch 59, 3-BET switch 60, and 5-BET switch 61. - In the subsequent S13, the game process to be described later shown in
FIG. 19 is performed, and the main process program is subsequently completed. - In the following, an explanation of the start acceptance process program executed in the
slot machine 1 is made with reference toFIG. 17 .FIG. 17 is a flowchart of the start acceptance process program. The start acceptance process is performed in S11 of the main process program shown inFIG. 16 . To achieve this object, the process first proceeds to S21 shown inFIG. 17 to determine whether a pre-determined time period (for example, 15 seconds) has elapsed. If it is determined that the pre-determined time period has not elapsed (S21: NO), the process proceeds to S23 without conducting any operation. However, if it is determined that the pre-determined time period has elapsed (S21: YES), an audiovisual presentation is made in the upperliquid crystal display 3 and the lowerliquid crystal display 4 in S22, and the process proceeds to S23. In S23, it is determined whether or not the spin (“SPIN/REPEAT BET”)button 12, 1-BET button 11, 3-BET button 13, and 5-BET button 14 have been operated. If it is determined that the 1-BET button 11 or the like has not been operated (S23: NO), the process returns to S21 to repeat the process described above. If it is determined that the 1-BET button 11 and the like have been operated (S23: YES), the process returns to the main process program shown inFIG. 16 , and proceeds to the lottery operation in S12 even if the machine is in the middle of an audiovisual presentation. - In the following, an explanation of the lottery program executed in the
slot machine 1 is made with reference toFIG. 18 .FIG. 18 is a flowchart of the lottery program. The lottery operation is performed in S12 of the main process program shown inFIG. 16 . To achieve this object, the process first proceeds to S31 shown inFIG. 18 to conduct the symbol determination process. The symbols to be statically displayed on the pay line L during the game (S42 shown inFIG. 19 below) are thereby determined for each of thevariable display windows number sampling circuit 56 so as to correspond to each of thevariable display windows FIG. 8 . When the symbols to be statically displayed on pay line L have been determined, a combination-determining process is performed in S32. In this combination-determining process, specifically, the winning combination and its payout are determined via the code numbers in S31 on the basis of the lottery table shown inFIG. 9 , as described earlier. - In S33, a reel condition determination process is performed. In this reel condition determination process, specifically, a pattern is determined after being selected from four patterns in which the
variable display windows 22 to 24 are either in the transmissive state or non-transmissive state. The determination is made based on the tables shown in FIGS. 10 to 15 and provided for each winning combination, and on random numbers sampled from a range of 0 to 7 by the randomnumber sampling circuit 56, as described above. For example, hitting a “7-7-7” in S32 causes therandom number 5 to be sampled in S33, whereupon pattern B is selected using the table shown inFIG. 10 . It is therefore determined that thevariable display window 22 is brought to a non-transmissive state, while thevariable display windows - The process subsequently returns to the main process program shown in
FIG. 16 , and proceeds to the game process in S13. - In the following, an explanation of the game process program executed in the
slot machine 1 is made with reference toFIG. 19 .FIG. 19 is a flowchart of the game process program. The game process is performed in S13 of the main process program shown inFIG. 16 . To achieve this object, rotation process is first performed according to S41 ofFIG. 19 . In this rotation process, specifically, thevariable display windows FIG. 18 , are changed from a non-transmissive state to a transmissive state. According to S11 ofFIG. 16 , thereels 220 on the back side ofvariable display windows FIG. 18 , also begin to be rotated based on the switch signals outputted from the SPIN/REPEAT BET switch 58, 1-BET switch 59, 3-BET switch 60, and 5-BET switch 61. On the other hand, thevariable display windows FIG. 18 , maintain their non-transmissive state, and the images of the symbol sets 241, 242, and 243 are scrolled. - Therefore, when, for example, pattern B is selected in S33 shown in
FIG. 18 , images of the symbol sets 241 are variably displayed on thevariable display window 22 in the non-transmissive state by scrolling in the non-transmissivevariable display window 22, through which thereels 220 located on the back side of the display are not visible. In thevariable display windows reels 220 located on the back sides of the displays start to rotate at the same time. The images of the symbol sets 242 and 243 formed on the peripheral surfaces of thereels 220 are variably displayed by scrolling in the transmissivevariable display windows reels 220 located on the back side of the displays are visible. The symbols are therefore variably displayed. - Regardless of whether or not a determination has been made that
variable display windows FIG. 18 , all of thereels 220 located on the back sides of the displays may begin to rotate in S41. - Subsequently, a stop control process is performed in S42. In the stop control process, specifically, the symbol sets 241, 242, and 243 are stopped in the
variable display windows reels 220 located on the back sides of thevariable display windows reels 220 and are scrolled on the transmissivevariable display windows reels 220 are visible. The symbols are thereby statically displayed. - Regardless of whether or not it has been determined that
variable display windows FIG. 18 , the rotation of all threereels 220 is stopped in S42 in cases in which all the threereels 220 located on the back sides of the displays begin to rotate in S41. - In S43, coins or other items equivalent to the pre-determined payout are discharged based on the table shown in
FIG. 9 and in accordance with the winning combination of symbols statically displayed on thevariable display windows FIG. 16 is completed, and the main process program shown inFIG. 16 is started As described above, theCPU 50 operates as the “reel control means” in executing S41 and S42 shown inFIG. 19 . - The
CPU 50 operates as the “display control means” in executing S41 and S42 shown inFIG. 19 . - The
CPU 50 operates as the “determining means” in executing S33 shown inFIG. 18 . - The
CPU 50 operates as the “game control means” in executing S43 shown inFIG. 19 . - Specifically, in the
slot machine 1 of the present embodiment, all thevariable display windows FIG. 1 . When the game is started, the symbols are variably or statically displayed by means of the four patterns, i.e., pattern A, pattern B, pattern C, and pattern D, which are either in a transmissive state or a non-transmissive state. This is done by combining the drawn winning combinations and the sampled random numbers in thevariable display windows FIG. 10 to 15). - In pattern A, all the
variable display windows reels 220 are variably or statically displayed via the transmissivevariable display windows reels 220 are visible. Therefore, it can be said that, in any of thevariable display windows - In pattern B, the
variable display window 22 remains in the non-transmissive state, while thevariable display windows variable display window 22 through which thecorresponding reel 220 is invisible. On the other hand, the symbol sets 242 and 243 formed on the peripheral surface of each of thereels 220 are variably or statically displayed in the transmissivevariable display windows respective reels 220 are visible. Therefore, it can be said that, the variable or static display of the symbols is performed by means of video reels in thevariable display window 22 in pattern B, and that the variable or static display of the symbols is performed by means of mechanical reels in thevariable display windows - In pattern C, the
variable display windows variable display window 24 is in a transmissive state. Therefore, the images of the symbol sets 241 and 242 are variably or statically displayed in the non-transmissivevariable display windows respective reels 220 are invisible. On the other hand, the symbol sets 243 formed on the peripheral surface of thereels 220 are variably or statically displayed in the transmissivevariable display window 24 through which thecorresponding reel 220 is visible. Therefore, it can be said that, the variable or static display of the symbols is performed by means of video reels in thevariable display windows variable display window 24. - In pattern D, the
variable display windows variable display windows respective reels 220 are invisible. Therefore, it can be said that the variable or static display of the symbols is performed by means of video reels in pattern D in any of thevariable display windows - Accordingly, in the
slot machine 1 of the present embodiment, thereels 220 visible through thevariable display windows liquid crystal display 4 are mechanically rotated and stopped (S41, S42), whereby the symbol sets 241, 242, and 243 provided around the periphery of thevariable display windows variable display windows variable display windows liquid crystal display 4 through which thereels 220 are invisible (S41, S42). It is thereby possible to jointly use “mechanical reels” and video reels in a superposed manner. - At this moment, a determination as to whether or not the
reels 220 in thevariable display windows liquid crystal display 4 have changed from a non-transmissive state to a transmissive state is made by selecting a pattern from among the four patterns (pattern A, pattern A, pattern A, and pattern A) in which the respective reels are in either the transmissive state or the non-transmissive state (S33). This determination is made based on the tables shown in FIGS. 10 to 15 and provided for each winning combination, and on the random numbers sampled from a range of 0 to 7 through the randomnumber sampling circuit 56. According to the determination made above, changing the state of the respective variable display windows in either the transmissive or non-transmissive state allows the following symbol combinations to be displayed and presented: symbols that are formed on the peripheral surfaces of thereels 220 and that are statically displayed via thevariable display windows liquid crystal display 4 through which thereels 220 are visible, and/or images of symbols statically displayed through thevariable display windows liquid crystal display 4 through which thereels 220 are invisible (S41, S42). - In the tables of FIGS. 10 to 15 provided for each winning combination, the probability distribution for each pattern's selection from among the four patterns (pattern A, pattern B, pattern C, and pattern D) is set for each winning combination with a different payout. Therefore, it becomes possible to heighten the player's expectations to obtain a payout, depending on the number of the
variable display windows liquid crystal display 4 through which thereels 220 are visible (or invisible). For example, the probability of pattern A being selected, in which all thevariable display windows liquid crystal display 4 are changed from the non-transmissive state to the transmissive state, is the highest when a winning combination of “7-7-7” is hit (refer to FIGS. 9 to 15). When the player sees that all of thevariable display windows liquid crystal display 4 have changed from the non-transmissive state to the transmissive state, the player's expectation is that a winning combination of “7-7-7” with the highest possible payout might have been hit. - The present invention is not limited to the embodiment described above, and may include various modifications made to it as long as the modifications do not deviate from the essence of the invention.
- For example, in the
slot machine 1 of the present embodiment, as described above, a determination as to whether or not thevariable display windows liquid crystal display 4 are changed from the non-transmissive state to the transmissive state is made by selecting a pattern from among the four patterns (pattern A, pattern B, pattern C, and pattern D; S33). The determination is made based on the tables provided for each winning combination shown in FIGS. 10 to 15, and on the random numbers sampled from a range of 0 to 7 by the randomnumber sampling circuit 56. However, the patterns in the transmissive or non-transmissive state are not limited to these four patterns (pattern A, pattern B, pattern C, and pattern D). For example, the following patterns may be used instead or in addition to the existing four patterns (pattern A, pattern B, pattern C, and pattern D): a pattern in which thevariable display window 23 is kept in the non-transmissive state, and thevariable display windows variable display window 24 is kept in the non-transmissive state, and thevariable display windows variable display windows variable display window 22 is changed from the non-transmissive state to the transmissive state; and a pattern in which thevariable display windows variable display window 23 is changed from the non-transmissive state to the transmissive state. In addition, changing the non-transmissive state to the transmissive state for thevariable display windows variable display windows FIG. 10 to 15. - Furthermore, in the
slot machine 1 according to present embodiment, all of thevariable display windows FIG. 17 is initiated. It is also possible, however, for the transmissive state of the previous game to be maintained until immediately prior to S41 in which the game process shown inFIG. 19 is performed for the current game. - Moreover, in the
slot machine 1 according to the present embodiment, the state of thevariable display windows FIG. 18 , is changed from the non-transmissive state to the transmissive state in the rotation process in S41 shown inFIG. 19 . It is also possible, however, to adopt an arrangement in which thevariable display windows FIG. 18 to have been changed from the non-transmissive state to the transmissive state, are changed from the non-transmissive state to the transmissive state immediately before the rotation has been stopped of thereels 220 located on the back sides of thevariable display windows FIG. 19 . In such case, however, the images of the symbol sets 241, 242, and 243 are variably displayed by scrolling in thevariable display windows - Moreover, in the
slot machine 1 according to present embodiment, the symbols to be statically displayed on the pay line L are determined for each of thevariable display windows number sampling circuit 56 in the lot drawing in S12, as shown inFIG. 8 and 9. It is also possible, however, to adopt an arrangement in which all the symbols to be statically displayed on the pay line L on thevariable display windows number sampling circuit 56. To achieve this object, the lottery table for winning combinations shown inFIG. 20 is used.FIG. 20 is an explanatory diagram showing the lottery table for winning combinations and the corresponding payouts. - In
FIG. 20 , the random numbers that are used in the lottery table for selecting the winning combination range from 0 to 1270. When the random numbers sampled via the randomnumber sampling circuit 56 fall within a range of 0 to 22, a winning combination of “7-7-7” is obtained, and the player receives a payout of “100.” Hereafter, the same procedures apply to the payouts of “5,” “3,” “2,” and “1,” based on the table shown inFIG. 20 . - If the random numbers sampled fall within a range of 248 to 1270, “a losing combination” is selected. In this case, a combination of symbols other than those described above are statically displayed on the pay line L in the
variable display windows - Moreover, the
slot machine 1 according to the present embodiment is used to play only ordinary games, but an arrangement may also be adopted in which, for example, an ordinary game is played and a free game is then played immediately after S13 inFIG. 16 . Such free games are generally designed to be advantageous for the player in many cases. For example, when the activities shift to a free game on the condition that specific symbols be statically displayed, the player can continuously play 10 games, 20 games, 30 games, or the like in accordance with the rank of the free game without betting any coins or the like. In such free games, the probability of winning various winning combinations is usually set higher. Therefore, the player can often win a large amount of coins. - Three reels are used in the
slot machine 1 according to the present embodiment, but the number of reels is not limited, and five or nine reels may also be used, for example. In particular, using nine reels can heighten the player's expectations of a payout by bringing only the variable display window in the exact center to a non-transmissive or transmissive state. - In the above-mentioned embodiment, the video reel has the same kind of columns of symbols as the mechanical reels have. However, the video reel may have different kinds of columns of symbols. By way of example, as shown in
FIG. 7B , the columns of symbols for the video reel may have more SEVEN (“7”) symbols such that it can be made more likely to win the SEVEN winning combination. Therefore, the player may enjoy various probabilities to win the winning combinations. - The present invention may be applied to gaming machines in which “mechanical reels” or video reels are used.
- Further, a gaming machine as described below may be provided.
- According to the present invention, a gaming machine (e.g., slot machine 1) comprises: a display device (e.g., lower liquid crystal device 4) including a plurality of display windows; a plurality of reels (e.g., reels 220), respective peripheral surfaces on which a plurality of symbols are arranged, the plurality of reels being disposed behind and in an opposing manner to the plurality of display windows of the display device (e.g., lower liquid crystal device 4), respectively; transparency control means (e.g., liquid crystal driving circuit 74) for making each of the plurality of display windows of the display device in a state disenabling a transmissive display of each of the plurality of reels (e.g., reels 220) disposed behind each of the display windows and a state enabling the transmissive display of each of the plurality of reels (e.g., reels 220) switchably; reel control means (e.g., CPU 50, S41, S42) for displaying variably and statically the plurality of symbols through the display windows by rotating and stopping the reels (e.g., reels 220) mechanically, which are visible through the display windows of the display device (e.g., lower liquid crystal device 4); display control means for displaying variably and statically the plurality of symbols in the display windows of the display device (e.g., lower liquid crystal device 4) which is in a state disenabling the transmissive display of each of the plurality of reels (e.g., reels 220) disposed behind; lottery means (e.g., CPU 50, S12) for conducting a lottery to select a combination of symbols to be composed of image symbols to be displayed statically in the display windows when the reels (e.g., reels 220) disposed behind and the symbols displayed statically thereon are not visible through the display windows of the display device (e.g., lower liquid crystal device 4) in the state disenabling the transmissive display of the plurality of reels disposed behind; determination means (e.g., CPU 50, S33) for determining a display window to be operated by the transparency control means (e.g., liquid crystal driving circuit 74) based on a combination of symbols selected by the lottery means (e.g., CPU 50, S12); and game control means (e.g., CPU 50, S43) for paying out respective payout amount corresponding to the selected winning combination when a combination of symbols selected by the lottery means (e.g., CPU 50, S12) includes one or more winning combination of symbols.
- As described above, according to the present invention, as visible reels through display windows of the display device are mechanically rotated and stopped, the plurality of symbols being disposed on the peripheral surfaces of the reels are displayed variably and statically through the display windows. And video images of a plurality of symbols are displayed variably and statically in display windows of the display device in a state disenabling the transmissive display of the reels provided behind the display device. Therefore, the “mecha-reel” and the video reel are employed in a superposed manner such that display effects of a combination of symbols comprising symbol images to be displayed statically in the display windows of the display device in a state disabling the transmissive display of the reels disposed behind the display device and/or symbols disposed on the reels to be displayed statically through the display windows of the display device in a state enabling the transmissive display of the reels disposed behind the display device as each of the display windows of the display device is determined to be from in the state disenabling the transmissive display to in the state enabling the transmissive display if the reels disposed behind the display device based on the combination of symbols selected by the lottery. Therefore, the player may expect higher probability to wind the payout depending on the number of display windows of the display device in the state enabling (or disenabling) the transmissive display of the reels.
